A=a^2, so A=4^2=16 , or 4*4=16
Step-by-step explanation:
All sides of a square are equal, so the length of the sides are all 4. Put 4 in for a in the formula A=a^2 or Area = side length squared.
A = 4^2
A = 4 * 4
A = 16
i believe it’s 165 because if u add 137 and 58 u get 195 and then subtract that from 360 and there’s ur answer
a. positive: 2 or 0; negative : 2 or 0; complex: 4or2or0
